As quoted from <5574@uhccux.uhcc.hawaii.edu> by grw@cartan.math.hawaii.edu (George R. Wilkens):
+---------------
| You need the tenex to download a binary file to a UN*X system, since simtel20
| is a VMS system. Once you get the file, just move it to RZSZ0525.TAR.Z, 
+---------------

Minor nitpick:  VMS doesn't require the "tenex" command.  The command is named
after the OS it supports:  "ten-ex", for TOPS10-extended.  This is one of a
family of operating systems (TOPS-10, Tenex, Tops-20, and Twenex) for the DEC
PDP-10 mainframe.  The reason it's provided is that the PDP-10 has 36-bit
words which don't cleanly split into bytes; ASCII files are stored as 5 7-bit
characters per word + 1 spare bit, while octet-oriented binary files are
stored as 4 8-bit characters per word + 4 spare bits.  The "tenex" command
causes ftp to unpack the files properly; "ascii" would do it wrong, and
"binary" (AKA "image") doesn't unpack bytes at all.
